Problems solved by technology

Since the seeds of Polyacaceae are hard seeds, there are many factors in the natural germination process that lead to a low success rate of seed germination, and the natural germination of seeds is far from being able to offset the reduction in resources
However, in traditional production, the germination rate of the seeds of Dacneaceae without any hormone treatment is often only about 50%, and the germination time is late and the emergence of seedlings is irregular, which limits the large-scale production of Dacceae seedlings.

Embodiment 1

[0025] In the first ten days of October, when the color of the seed shells of the seeds of Polyacaceae changed from green to yellowish-brown or chestnut brown, when they were hard and translucent, the seeds were collected, and fresh seeds of Polyacaceae were obtained. Spread the collected fresh Tacau seeds in a ventilated room without direct sunlight, manually remove impurities such as shells, twigs, and leaves, and remove seeds with wormholes, irregular shapes, damages, and too small shapes. Soak the selected seeds of Polyacaceae in clear water for 40 hours to make them fully absorb water and swell; then fully stir the seeds of Polyacaceae in clear water, then let them stand to remove unfulfilled seeds or empty shells floating on the water surface, and finally repeat Rub and wash the remaining seeds. After washing, remove and drain the tahina seeds. Soak the washed and drained Dosuke seeds in a 0.5% potassium permanganate solution for 50 minutes, then take them out, rinse the...

Embodiment 2

[0027] In mid-October, when the color of the seed shells of the seeds of Polyacaceae changed from green to yellowish-brown or chestnut brown, when they were hard and translucent, the seeds were collected to obtain fresh seeds of Polyacaceae. Spread the collected fresh Tacau seeds in a ventilated room without direct sunlight, manually remove impurities such as shells, twigs, and leaves, and remove seeds with wormholes, irregular shapes, damages, and too small shapes. Soak the selected seeds of Polyacaceae in clear water for 48 hours to make them fully absorb water and swell; then fully stir the seeds of Polyacaceae in clear water, then let them stand to remove unfulfilled seeds or empty shells floating on the water surface, and finally repeat Rub and wash the remaining seeds. After washing, remove and drain the tahina seeds. Soak the washed and drained Dosuke seeds in a 0.5% potassium permanganate solution for 60 minutes, then take them out, rinse them with clean water, and dry...

Embodiment 3

[0029] In the first ten days of November, when the color of the seed shells of the seeds of Polyacaceae changed from green to yellowish brown or chestnut brown, when they were hard and translucent, the seeds were collected, and fresh seeds of Polyacaceae were obtained. Spread the collected fresh Tacau seeds in a ventilated room without direct sunlight, manually remove impurities such as shells, twigs, and leaves, and remove seeds with wormholes, irregular shapes, damages, and too small shapes.

Abstract

The invention discloses a method for promoting germination of lithocarpus polystachyus rehd seeds. The method is carried out through the steps of collecting seeds, pretreating the seeds, preparing a sand bed, performing sand storage for accelerating germination and performing breeding management and protection. Specifically, the method specifically comprises the following steps: collecting mature lithocarpus polystachyus rehd seeds in October and November, performing seed selection, seed washing, sterilization and gibberellin solution seed soaking treatment, performing sand storage for accelerating germination, and performing breeding management and protection to obtain germinated lithocarpus polystachyus rehd seeds. The dormancy period of the lithocarpus polystachyus rehd seeds is broken through by using gibberellin solution, the germination period of the seeds is obviously shortened, the germination rate of the lithocarpus polystachyus rehd seeds is improved, the germination time of the lithocarpus polystachyus rehd seeds is advanced for nearly 20 days, and the germination rate is improved by over 20 percent. The method is simple in process operation and low in cost and has high economic benefits, social benefits and ecological benefits, and rapid, neat and high-efficiency germination of the lithocarpus polystachyus rehd seeds can be promoted.

Description

technical field [0001] The invention relates to a method for accelerating the germination of seeds, in particular to a method for promoting the germination of polyacaceae seeds. Background technique [0002] Tachiko ( Lithocarpus polystachyus Rehd ), also known as sweet tea, is an evergreen tree of the Fagaceae (Fagaceae) genus Lithocarpus (Lithocarpus), and is a traditional folk herbal medicine and health drink plant in my country. Its leaves contain sweet tea, which is a natural sweetener with high sweetness, low heat and non-toxicity. In recent years, studies have confirmed that Coryne multiflorum is also rich in 17 kinds of amino acids, various trace elements, vitamins, phloridin, trilobatin, and various flavonoids, polyphenols, triterpenes and other compounds that are necessary for the human body. Human free radicals, anti-aging, anti-allergic, dilating blood vessels, regulating vascular permeability, preventing arteriosclerosis, lowering blood pressure, lowering lipi...
